Lessons

The "lessons"
below could also be described as animations or even as slide shows. In fact, we are not exactly sure what to call them! They illustrate concepts and steps required to carry out different operations. They have audio commentary although they can be viewed with just the text. The lessons developed so far include six on fractions, three on percent, and one on long division.

The links below will open the lessons in a new window. There is a navigation bar at the bottom each lesson that will allow you to:

Fractions Lessons

#1: Introducing Fractions (2:42 min.)
This lesson introduces the concept of fractions as being part of one whole unit. It illustrates how numerators and denominators are used when writing and saying fractions.

#2: Equivalent Fractions (3:41 min.)
The concept of equivalency of fractions is explored with examples of finding equivalent fractions by multiplying and dividing the numerator and denominator by the same number.

#3: Common Denominators (4:10 min.)
The need for and use of common denominators are discussed in this brief lesson. Guidance on how to find common denominators using least common multiples is shown.

#5: Simplifying Fractions (3:12 min.)
Two different methods of how to simplify fractions are shown. One involves dividing the numerator and denominator by their greatest common factor. The other uses more of a "keep dividing until you can't divide anymore" method.
